Genes affected

RXRG (HGNC:10479): (retinoid X receptor gamma) This gene encodes a member of the retinoid X receptor (RXR) family of nuclear receptors which are involved in mediating the antiproliferative effects of retinoic acid (RA). This receptor forms dimers with the retinoic acid, thyroid hormone, and vitamin D receptors, increasing both DNA binding and transcriptional function on their respective response elements. This gene is expressed at significantly lower levels in non-small cell lung cancer cells. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jun 2010]

The c.211C>G (p.R71G) alteration is located in exon 2 (coding exon 2) of the RXRG gene. This alteration results from a C to G substitution at nucleotide position 211, causing the arginine (R) at amino acid position 71 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
